Senior LLM Backend Engineer

We are looking for a Senior Backend Engineer with a strong focus on Large Language Models (LLMs) to join one of our product squads. You’ll be responsible for designing, implementing, and optimising LLM-powered features, working closely with product managers, designers, and engineers to bring AI capabilities directly into our products. You’ll own the full lifecycle of LLM integration, from experimentation and prototyping, to production deployment, to ongoing optimisation. You’ll also help shape our AI architecture, ensuring that LLM features are scalable, efficient, and cost-effective. Our backend is written in Python, and you’ll use it alongside AI integration tools, APIs, and frameworks to create innovative features in areas such as personalisation, conversational interfaces, AI-assisted analytics, and automated decision-making.
